LUNG CANCER :

Cancer is the uncontrolled growth of abnormal cells. Tumor -->larger and more numerous 2 gives

1.Benign tumor.2.Malignant tumor.Cancer can be either PRIMARY or SECONDARY.

Lung cancer is divided into

1.small cell lung cancer.

2.Non-small cell lung cancer

CXR

CT Scans

MRI

Sputum cytology

Fibreoptic bronchoscopy

Transthoracic fine needle aspiration

DIAGNOSIS

RISK FACTOR: Smoking.

Radon.

Asbestos.

Air pollution .

TREATMENT :

Lobectomy.

Segmentectomy (wedge Resection).

pneumonectomy.

LOBECTOMY :It is a removal of a lobe.

1.open type

2.VATS.

PNEUMONECTOMY :

• Removal of entire lung.

1.simple pneumonectomy.

2.Extrapleural pneumonectomy. (EPP)
